First, freak out about the philosophical implications of the Force being real, since I'm a philosophy major.
Probably use my enhanced senses and foresight to learn some interesting things - maybe put my talents to use in information gathering.
Also, I'd probably eschew traditional transportation and run/jump everywhere with force speed and force jump. Maybe become the world's best free-runner?
Also become a part time medical professional with force heal.
And I'd train others that I thought might be responsible enough to use it properly, which would ultimately end in me making a mistake and having an epic showdown with a former student turned rival.
So pretty much either part-time Jedi-scholar, part time agent or private investigator, part time healer, part time teacher, and part time roaming around looking for interesting ways to apply my powers. Edit: (wait, that's basically jedi knight minus the spaceship...)
